Oklahoma State Fair--Which One?

I noticed that there is an Oklahoma State Fair at Oklahoma City from Sept. 12 to 22, and then a Tulsa State Fair from Sept. 26 to Oct. 6. I'm kind of interested in the Tulsa one, because there's a 2-day Oklahoma Sugar Arts Show Sept. 28 and 29 during the fair, but is the Tulsa fair as bit as the other one? Would it be a mistake to miss it?
